Yes it's a good manifold. Also, Crane manufactured the letter cams for Ford. Even though they came in a Ford box, they very well could have came with Crane instructions, I've never had one new in the box, so I can't say for sure.

Crane also sold the same cams under their own part #'s.

To answer your question about quality, Comp and Crane were the big names. Crane recently went out of business, but has since been bought by S&S cycles and is back in the game.

Interesting.

Have you got any cross reference numbers for the Ford 's alphabetical letters as to the Crane Cam numbers ?
